Specification of Letters Patent.

Application filed August 6, 1910.

Patented Sept. 2%, 1910. Serial No. 575,953.

To all whom it may concern:

Be it known that I, J AMES NATHAN l ALL, a citizen of the United States, residing at Hornbeck, in the parish of Vernon and State of Louisiana, have invented a new and useful Churn; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention about to be set forth, belongs to the art of churns, and it particularly pertains to a new and useful churn of the hand-operated type.

In this particular churn, the object of the invention is to improve the structural details thereof, namely, the frame for the support and mounting of the shafts of the beveled spur-gear and the beveled pinions.

Another feature of the invention is the provision of means for preventing lateral or upward displacement of the cover of the receptacle, and furthermore to prevent downward displacement of a hollow shaft, which carries the lower beveled pinion.

The invention aims as a further object, to provide a novel form of churning element, and to furthermore simplify the structure of churn set forth in the Patent N 0. 960,680.

The drawings only disclose one improved form of the invention, but, however, in practical fields, this form may require changes and alterations, to which the applicant is en titled, provided such changes and alterations are comprehended by the claims herewith appended.

Referring to the drawings :Figure 1 is a perspective view of a churn embodying the various features of the invention. Fig. 2 is vertical sectional view through the receptacle of the churn, showing the churning element in one position, and disclosing other parts in elevation. Fig. 3 is a vertical sectional View through the frame or support for the shafts of the beveled spur gear and the beveled pinions. Fig. 4 is an enlarged detail sectional view through a portion of a cover of the churns receptacle, disclosing the means for preventing the downward movement of the hollow shaft, which carries the lower beveled pinion. Fig. 5 is an elevation of the churning element, showing the cooperating parts thereof in different positions to that shown in Fig. 2. Fig. 6 is another elevation of the churning element, showing parts in section to illustrate the mounting of one of the parts of the churning element within the other. 7 is a sectional view on line 7-7 of Fig. 6.

Referring to the annexed drawings, 1 represents the churns receptacle, which is provided with a cover or closure 2. Mounted and secured to the cover or closure is a frame 3, which may be made of any suitable material, but preferably metal in the form of a casting. This frame or casting is formed in one single piece and is provided with two inwardly turned ends t, which may be placed closely and snugly together. If necessary these two inwardly turned ends may be rigidly connected together by any suitable means, and if the casting or frame is made of malleable iron or similar material these ends may be welded together. These two inwardly turned ends form an extension, which provides novel bearings for the crank shaft 5, the vertically arranged solid shaft 6 (which is telescopically received by the hollow shaft 7). This hollow shaft 7 is also mounted in one of the bearings 8, 9 and 10, as shown clearly in Fig. 8. The crank shaft 5, at its end 11, is conical, in order to have a thrust bearing in the bearing 9.

12 represents a beveled spur gear, which is mounted and secured upon the shaft 5 by means of the screw" 13, and with which beveled spur gear the upper and lower beveled pinions 14 and 15 mesh. The upper beveled pinion 14; is carried by and rotatable with the solid shaft 6, there being a suitable screw 16 for holding it in place. The beveled pinion 15 is secured to the hollow shaft 7 by means of the screw 17, in order to rotate with the shaft 7 A portion of the crank shaft 5 is mounted in a bearing 18 of the vertical part 19 0f the frame or casting 3. The casting or frame 3 is fastened to the cover or closure 2 by means of the plate 20, which is in turn fastened to the closure or cover, as shown in 21. This plate 20 is so formed, as shown at 22, as to receive the lower horizontal portion 23 of the frame or casting.

The frame or casting at each lower side is provided with downwardly projecting lugs 24, there only being one shown, reference being had to Fig. 1. These lugs 24 are received in the keepers 25, which are secured to the churns receptacle, as shown at 26. There are two of these keepers employed, but it is only deemed necessary to illustrate one of them. By the production of these lugs and keepers, the cover or closure is prevent ed from rotary displacement.

At one corner of the plate 20 an ear or lug 27 is formed, in which an aperture 28 is provided. Extending through the aperture is a bail-shaped spring member 29, which is formed with downwardly extending hooked ends 80. These hooked ends are designed to engage depressions 31 of the churns receptacle, in order to prevent upward removal or displacement of the cover or closure. The bail-shaped spring member 29 has sufficient resiliency whereby one of the hooked ends, at the end 32 of the said member, may be disengaged from its depression, when it is desired to remove the cover or closure. The shaft 5 is provided with a crank and handle 83 and 34, whereby beveled spur gear and the pinions may be operated.

To prevent the hollow shaft 7 from down ward displacement, a threaded bushing or sleeve 35 is provided, which is threaded into the cover or closure 2, as shown clearly in Fig. 4, and is designed to abut against the under surface of the beveled pinion 15. It will be seen that the beveled pinion is secured to the shaft 7, therefore the shaft is prevented from moving downwardly, through the contacting of the pinion and the sleeve or bushing 35.

36 represents a lock-nut, which is threaded to the bushing or sleeve 35, in order to securely hold and lock the bushing properly in place, there being a washer 37 located between the lock-nut and the cover or closure 2, in order to compensate for wear upon the cover or closure. The bushing or sleeve 35 is provided with depressions 38, which are designed to receive any suitable spanner (not shown) in order to screw the bushing or sleeve in place.

The churning element 39 comprises the two parts 40 and 41. The part 40 is provided with oppositely extending twisted arms 42, and is operable in the part 41 (which is rectangular in contour). The vertical sides of the rectangular part 41 is provided with inwardly extending twisted arms 43, which intermesh with the arms of the part 40. This inter-meshing feature is obtained, owing to the fact that the arms 48 are arranged in staggered relation with one another, in order that the arms of the part 40 will pass between them. The part 41 of the churning element is movable with the hollow shaft. 7 while the part 40 is movable with the shaft 6. The part 40 is provided with a plate 44, between which and the part 40, the shaft 6 is threaded, there being a lock-nut 45, for making this connection a secure one. The part 41 is also provided with a plate 46, which securely clamps the lower rectangular portion of the hollow shaft 7. The plates 44 and 46 are secured by means of bolts or rivets or other suitable means 47.

The lower spindle 48 of the part 40 is provided with a thrust bearing 49 in the adjustable plug 50. This plug 50 is threaded into and through the lower horizontal part or bar 51 of the part 41 of the churning element, whereby the same may be readily adjusted, in order to insure a proper thrust bearing for the said spindle.

It will be clearly noted, from the foregoing, in connection with the drawings, that by manipulating the handle 84, motion will be imparted to the beveled spur gear 12, which in turn will impart opposite rotary motions to the beveled pinions 14 and 15. Being that the beveled pinions 14 and 15 are movable with the shafts 6 and 7, the cooperating parts of the churning element will be imparted movements corresponding to the motions of the beveled pinions.

The invention having been set forth, what is claimed as new and useful is 1. In a churn, a churn body or receptacle, a cover therefor, telescopically arranged centrally disposed shafts penetrating the cover and provided with churning elements, a rectangular casting secured to the cover, a crank shaft provided with a beveled spur gear mounted in a bearing of the casting, said casting having inwardly turned ends arranged adjacent one another forming bearings for the telescopically arranged shafts and the extremity of the crank shaft, and beveled pinions carried by the telescopically arranged shafts to mesh with the beveled spur gear, whereby motion may be imparted to the churning elements.

2. In a driving mechanism for a churning element, the combination of a pair of telescopically arranged shafts, and a crank shaft, of a rectangular frame or casting having inwardly turned adjacent ends forming bearings for the telescopically arranged shaft and the crank shaft.

3. In a driving mechanism for a churning element, the combination of a pair of telescopically arranged shafts, and a crank shaft, of a rectangular frame or casting having inwardly turned adjacent ends forming bearings for the telescopically arranged shaft and the crank shaft, a beveled spur gear carried by the crank shaft, and beveled pinions carried by the telescopically arranged shafts to mesh with the spur gear whereby motion may be imparted to the telescopically arranged shafts.

4. In a driving mechanism for a churning element, the combination of a churns cover and telescopically arranged shafts penetrating the cover, of a rectangular casting having inwardly turned adjacent ends forming bearings for the shafts, means for preventing downward displacement of one of the shafts, and mechanism for rotating the telescopically arranged shafts.

5. In a driving mechanism for a churning element, the combination of a churns cover and telescopically arranged shafts penetrating the cover, of a rectangular casting having inwardly turned adjacent ends forming bearings for the shafts, means for pre- Venting downward displacement of one of the shafts a crank shaft mounted in said casting having its extremity mounted in a thrust bearing of the inwardly turned ends and provided with a beveled spur gear, and beveled pinions carried by the telescopically arranged shafts, whereby motion may be imparted to them through the medium of the spur gear.

In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing witnesses.
